SOCD report detected: (AP watchdog expired)

I experienced this error yesterday on my new MBA M1 too for the first time with 11.5.2 installed.

I had nothing external connected to my Mac, not even the power cable (since I read that some claim this could be related to connected external WD drives).

I found under /Library/Logs/DiagnosticReports an panic-base-xxx.paninc file:

{"bug_type":"210","timestamp":"PRIVATE","os_version":"macOS 11.5.2 (20G95)","incident_id":"PRIVATE"}

"SOCDPanicString" : "SOCD report detected: (AP watchdog expired)",

"binaryImages" : []

}

Decoding the SOCDContainer entry as base64 looks like a small part of a core-dump or something similar to me.

But I have no clue to witch binary it could match? But sure an Apple engineer would have this missing information.

And since this error in the wild since a while now they should have at least a clue what could causing it. But there is just silence, as always.

"SOCDContainer" : "PRIVATE",

perhaps since any debug information seems to be hidden with cryptography, it further points to relationship with SEP & sepOS. maybe this is the case with all crash reports though.

SOCD = system on chip daemon?

AP = application processor ?

then we could even speculate that Rosetta 2 is somehow at play here as well.

Mine (M1 mini, 2020) went back to Apple. Too many stability issues. Time Machine backups getting dropped and marked read-only, Terrible battery drain on Apple branded bluetooth keyboards and trackpads, SOCD, screen flickering that took many restarts to go away, USB devices needing to be unplugged and replugged after each reboot, etc. etc.

I will wait for the next hardware iteration.

Nothing from Apple at this point. It might be external drive related for a lot of folks but my issue on the Mac Mini M1 certainly had to do with connecting to my LG monitor. Didn't work via HDMI or DisplayPort. I returned it and ordered an Air, will see how that goes.

If you read further into the string of info it appears it is happening to people without a hard drive connected as well. I have a hard drive connected and it happened to me. Others said no hard drive connected and it still happens. I haven't done the new update as it was reported the update made it worse. I called apple and second tier support wouldn't acknowledge the problem or knowing anything about it. Sent in all my reports and info. Hoping they acknowledge they are at least aware and working on it.

Same story. Watching YouTube videos, random solid green screen, reboot. Mini M1, 16gb.

USB C SSD connected which I need because 256gb is not enough and more is too expensive for me ;).

I should add; Some days ago I got an error telling me the drive had issues and could only be used for reading, not writing, and that I should reformat it. So I copied everything to my NAS, reformatted the drive, copied it back.

Do not call apple support on this issue unless you want to hear a script to do all of what this user already did. Very frustrating

Yeah, I know how that can go. But Apple is now offering gift cards for trade in of M1 Mac Minis. Just sayin. IMHO that's way more convenient than jumping through numerous hoops for Apple support.

Received and tested the USB C to Mini DisplayPort cable, machine crashes with this setup more than with HDMI cable. It doesn't last 2 minutes before crashing. I really think this unit is defective. The MacBook Air works with no issues at all. I don't think getting a new monitor is going to resolve this. I am thinking the issue is bigger. Going to wipe and do a new software load and if that doesn't resolve it, I am sending it back.

You must be one of the lucky ones who actually has the option of sending it back. Within 15 days of your purchase? I think most of us didn't discover this problem until it was far too late to "send it back".

Frequent shutdowns / resets create their own problems. My Time Machine drive sometimes stops working and goes read-only, when I shutdown or restart. It can sometimes be corrected by another restart, but often it needs to be reinitialized. Also, my USB devices always disappear when I restart the computer. This requires me to re-plug the USB cable after each restart.

Apple is in the process of shipping me my THIRD M1 Mac mini. Hopefully I will have better results.

Heck, if I could get Apple to send me one replacement it would be... eBay here I come.

Well, that's a new one:

panic(cpu 0 caller 0xfffffe002fb5a954): Sleep transition timed out after 35 seconds while calling power state change callbacks. Suspected bundle: com.apple.driver.AppleT8103PCIeC

I had the same issue today for the first time, on MacBook Pro M1. I've been using the computer for 4 months by now, and I've been running the MacOS 12.0.1 from the very first day it was released, not further updates after that one.

Nothing was connect in the Mac, no external driver, no bluetooth, nothing. It happened while I was watching Amazon Prime Video on Microsoft Edge Browser.

Yep, I'm getting this issue on the 2021 16" M1 Pro MacBook Pro as well. Happens about twice a day, have wiped + reinstalled macOS twice and it still happens.

Been quite frustrating, the genius bar could not reproduce the issue. Left it with them again, hopefully they can reproduce it this time. I notice it happens more when the battery is low and it is unplugged.

Have you had any luck trying to fix it?

I decided to check the support page. I selected MacMini-->More. I typed that my mac mini computer reboots on its own. It told me to take the computer to a repair location. After seeing all these replies after one year Apple has determined that I should do as you suggested.

Mac Mini M1 - 2TB - 16GB, this SOCD + green screen crash has been happening a few times in the last 2-3 weeks. There are quite a few external drives attached (working with lots of photo and video projects).

This is a machine that had already had its innards replaced shortly after purchase because of frequent pink-screen crashes and rapid spontaneous reboots.

For now just adding my voice to the thread and will follow up with more details when I have them. Not looking forward to having to go through Support's checklists but will do.

I should clarify that I sent the system to Apple, and on their bench wherever that was, they ran whatever they run and replaced that stuff.

I didn't do any "diagnostics" at an Apple bar or at home. I did send them logs at least three times, and got tired of them not responding so just asked to ship it to them.
